Re: Chapter numbering not appearing (Word 2007)

This appears to be caused by the Frame that is part of the Heading 1 style. If you alter the style to remove the frame and then change the paragraph indents to get the same position on the page then the page numbers will work as expected. If you move the first line far enough to the left then it won't appear on the page as per your frame layout.

Re: Chapter numbering not appearing (Word 2007)

Does Word 2007 have the Page Number Formatting dialog where the style associated with the chapter number (and the hyphen separator) are assigned? Can you see whether this information is accessible in the "upconverted" document?
